Yin Chiao is probably the most popular remedy for Cold and Flu in the world, especially when you factor in the Asian users.
And you know there is just something exotic about Chinese herbs. Those ancient healers knew stuff, all the way back to the Yellow Emperor.
Take 3-4 tablets every 4 hours at the first sign of a cold: fever, slight chills, headaches, thirst, cough, sore throat. Yin Chiao helps disperse "Wind heat". It also clear heat and resolves toxicity.
